The audit trail generator tool is included in the distribution package and is located in the tools directory. This tool can be used to generate the CME audit trail files.

It has the following arguments:

LogFileToAnalyse - The path to the *.summary log file that will be used as a source file for audit trail data.
OutputFieldDelimiter - The delimiter between fields in the resulting audit file (by default, the comma is used).
CMETradeDayStartTimeUtc - The CME trade day start time in UTC (by default, 4:45 CST - 9:45 UTC is used).

Example:

$ onixs-cme-audit-trail-generator SESSION_NAME.summary

Note: The format of the *.summary log file and audit trail requirements for CME iLink 3 differs from the iLink 2. Therefore, there are two different audit trail generators. This means that the audit trail generator for iLink 2 cannot be used to generate audit trail files for iLink 3.
